摘要：
An optical apparatus includes a zoom optical system including a focus lens unit, an operation portion configured to manually and mechanically change a focal length of the zoom optical system, and a controller configured to control the focus lens unit so as to move along a track depending on an object distance in an operation of the operation portion. The controller moves the focus lens unit to a second position that is different from a first position that is a position of the focus lens unit in disconnecting a power when a first focal length that is a focal length of the zoom optical system in disconnecting the power is different from a second focal length that is a focal length of the zoom optical system in reconnecting the power.
